Well, I wouldn't say he isn't repping anything. Cause he still has all the Kx hands in his range.
So mainly depends how we see the opponent and how bluff-like + of course what kind of image we had on the table.

If we assume that he is capable of bluffing in those spots then sure, why not to Call down, the odds ain't that bad either and he could even Check/Raise time to time with weaker PPs for protection.
